摘　　要：电压互感器(TV)二次回路压降大小直接影响计量的准确性。通过对二次压降存在的主要问题进行分析,给出降低二次压降的方法,并做出相关比较和总结,推荐使用自动跟踪补偿法和光纤传输法。The secondary loop voltage drop in a voltage transformer directly influence the accuracy of metering. Cause analysis are made on existing main problems and methods for voltage drop is recomended for secondary loop voltage drop, and then present nine kinds of method with which can reduce the secondary loop voltage drop, and relative comparison and summary on them are made. The Automatic Tracking and Compensating Method and the Fiber Optical Transmission Method are recommended among all the nine kinds of methods.
